Summary

Microsoft 365 Copilot now integrates past Copilot chats into search results, allowing users to retrieve their historical conversations from notebooks, agents, and the main chat. This feature, requiring a Copilot license, rolls out from November 2025 to March 2026, with no admin action needed.

Details

Updated February 17, 2026: We have updated the timeline. Rollout on mobile platforms (Android and iOS) are in progress, expected completion by 3/30. Thank you for your patience. 

We’re introducing a new capability that enhances Microsoft Copilot by integrating historical Copilot conversations into Microsoft Search. This update allows users to retrieve past interactions—including chats from notebooks, agents, and the main Copilot chat interface—directly within the search results page (SERP). A new “Copilot Chats” data source will also appear in the right rail, enabling users to scope their search specifically to Copilot-generated content.

A Microsoft 365 Copilot license is required to access this feature.

This message is associated with Microsoft 365 Roadmap ID 506751.

When this will happen:
  • Public Preview (Worldwide): Rolling out early November 2025; expected completion by mid-November 2025.

  • What will happen:
    • Users will be able to search and retrieve historical Copilot conversations from:
      • Notebooks
      • Agents
      • The main Copilot chat interface
    • A new “Copilot Chats” data source will appear in the right rail of the search results page: 
    • user settings

    • Users can scope their search to only include Copilot-generated content.
    • Each user will only have access to their own Copilot conversations.
    • No changes to tenant-wide settings or permissions are required.
What you can do to prepare:
  • No action is required from tenant admins at this time.
  • You may wish to inform your users about this new search capability to help them take full advantage of Copilot.
